I like it. I like its association with peace in art and poetry. That makes the name interesting for me. I also like the sound of the name. I love that it is clunky, because I get tired of all the flowy and overly soft girls' names that are popular right now. Clunky and consonant heavy names can sound beautiful too. They sound strong and substantial.

I don't know if I would ever use Arcadia because it does remind me of arcade, and I am not normally a fan of place names.
